Alternative history

Alternative History

That did NOT happen to us

By Eugene V. Bobukh


Project orion

Project Orion

Spaceship driven by nuclear explosions.

Yes this is absolutely possible.

Earth to LRO fallout: 0.1-10 Mt.

Saturn manned roundtrip: 1 year in 1970s.

Alpha Centauri: ~80 years in 1980s.

Proposed: 1946.

Incepted: 1958. Serious design and testing.

Killed: 1963 by Partial Nuclear Test Ban Treaty (!!!) and other political issues.

To those familiar with Soviet sci-fi: see “Хиус”, 1959.

After Chernobyl and Fukushima, don’t even propose that aloud anymore…


Project nerva

Project NERVA

  • (Thermal) Nuclear Engine for Rocket Vehicle Application

  • Test-ready by ~1969

    • 8340 m/s in vacuum

    • T/M: 0.18 to 0.98 (with a rocket stage)

  • Planned Mars flight in 1978 and Moon base in 1981

  • Ended in 1972 by budget cuts

  • USSR had a similar engine RD-0410

    • 1965 – 1985

    • 9000 m/s

    • T/M = 1.76 (engine only)

RD-0410 test


Manned venus flyby

Manned Venus flyby

  • Based on lunar Apollo technology

  • Established: 1968.

  • Planned:

    • Launch 1973

    • Return 1974 (11 months expedition)

    • Crew: 3 people

  • Who needs a man on or near Venus?

    • 500 C, 95 bars, opaque atmosphere, H2SO4 rain

    • Robots obviously won

Project OTRAG Credit of http://www.astronautix.com/lvs/otrag.htm

  • Idea by Lutz Kayer:

    • Modular “cheap and dirty” rockets

    • Times mass production

    • ???

    • Profit

  • 1975 – 1982

  • Poor choice of countries

    • Congo, Libya

  • Test-flown

  • Killed by economic & political pressure

    • “…Crude Soviet-source disinformation was eagerly picked up and given credibility by the American mainstream media…”


Delta clipper dc xa 1991 96 the strangest tale ever

Delta Clipper (DC-XA), 1991-96The strangest tale ever!

How many people here recognize this machine?

This thing flew. For real.

Yes, a mockup only. But totally feasible.

A single-stage, completely reusable orbital rocket.

Built by McDonnell Douglas & Strategic Defense Initiative Organization in 1991. Test flown.

Transferred to NASA in 1993. Improved. Crashed in 1996.

Closed.

WTF???

Done

  • There were many more… but better not dive into alternative history.
